[gm45] Running piglit/occlusion-query-discard locks GPU

Binary package hint: xserver-xorg-video-intel

As bug title :).

Furthermore, the GPU never recovers from this, although the hangcheck timer is clearly trying something. dmesg gets spammed with messages like:

 [ 238.510067] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting 39391 at 39265)

Hi, I may have a similar bug or even a duplicate. See bug #642825 if you are interested.

For me, running normal updates fixed half of the issue - I did at one point get the 'render ring head not reset to zero' output, but after updates I only get 'hangcheck_timer_elapsed'.

Hi, same problem here. I am using clean install od Kubuntu 10.10 with latest updates. After boot, the compositing is temporarily disabled. I am able to resume the compositing from KDE Control Center a then everything is working fine. After some random time, when I use some KWin effect (Tab-switching , desktop switching, desktop grid, ...), KDE hangs and syslog become flooded by messages described in this bug.

HW : HP 2230s, Intel GM45 chipset
xserver-xorg-video-intel 2:2.12.0-ubuntu5
Kubuntu 10.10 64bit

Same problem here, but in my case it's sporadic and not 100% reproducible.

[drm:init_ring_common] *ERROR* render ring head not reset to zero ctl 00000000 head 02001000 ...

Occurs in periods of innactivity, but it's unrelated with suspension or hibernate (I have them disabled). Some times hard to see because of turning off the screen hides the message.

Ubuntu 10.10 up-to-date

In my case HP Elitebook 6930p, Intel GMA 4500MHD

This thread marks the fix as 'released' but could anyone please point out to me how to fix it in kubuntu 10.10 x64?

The symptoms here are extremely generic - there are a vast variety of driver bugs that can produce the same log messages.

This particular driver bug has been fixed; if you're still seeing something with similar symptoms then you're seeing a different bug (and should probably file a new bug, or try disabling some effects in an attempt to not trigger the bug you're hitting).
